Experimental Study on Effect of Welding Parameters of Friction Stir Welding (FSW) on Aluminium AA5083 T-joint

Abstract

Friction Stir Welding (FSW) is a high reliability solid state joining process that promote energy efficient, versatile and environmental friendly. In this study, experiments were conducted to investigate the effects of FSW welding parameter for different transverse speeds (i.e., 67, 82 and 92 mm minG1) and rotational speeds (i.e., 490, 653 and 910 rpm) on the weld quality of Aluminium Alloy (AA) 5083 T-joint. A customized fixture had been made to clamp 2 pieces of AA5083 and AISI H13 cone with thread tool shape is used as tool pin profiles in this present study. Five samples were successfully prepared and three mechanical tests were carried to validate the specimens such as visual inspection on the surface weld, macro inspection and tensile test. It was found that the suitable welding parameter obtained is rotational speed 910 rpm and transverse speed 92 mm minG1. The specimen produces no defect on the weld surface and cross section as well as obtained highest ultimate tensile strength of 90.33 Mpa.
